Static link aggregation comprises:

Setting the aggregation state of each member port
Choosing a reference port
The system chooses a reference port from the member ports that are in the up state and have the same
class-two configurations as the aggregate interface.
The candidate ports are sorted by aggregation priority, duplex, and speed in the following order:
•
Lowest aggregation priority value
•
Full duplex/high speed
•
Full duplex/low speed
•
Half duplex/high speed
•
Half duplex/low speed
The one at the top is chosen as the reference port. If two ports have the same aggregation priority, duplex
mode, and speed, the one with the lower port number is chosen.
Setting the aggregation state of each member port
After choosing the reference port, the static aggregation group sets the aggregation state of each
member port as shown in
.
